Daisy was Viktor's childhood friend who was raised by his family. Daisy was chosen by Neclord to be his bride, and Viktor tried to defeat Neclord but was instead mortally wounded (he recovers due to a sacrificial jizo that Daisy gave him a while beforehand). Seeing this, Daisy killed herself. When Viktor returned to Northwindow to fight with Neclord, Neclord created a fake Daisy to tempt Viktor. However, Viktor decapitated the fake Daisy with the Zodiac Sword. - KoRnholio
